The finish clock on the video is correct, but it's very likely for third wave runners who started forty minutes after the first wave. So they finished in 4:09, but 4:49 from the start of the elite race. Made no sense to me at first because I was in the first wave, was walking back to my hotel 4:09 after my start, but heard nothing. Tacking on forty minutes makes the timeline add up, as I was napping by then (and wondering why sirens were interrupting my nap).
